Definitions

  • the invention relates to a process for the continuous production of metal-clad laminates, in particular, for the manufacture of electric printed circuit boards, consisting of an electrically insulating core layer and a metal foil covering one or both surfaces of this layer, wherein the metal foil unwound from a supply roll and pre-heated is bonded in a dual-belt press under the influence of pressure and heat to the core layer.
  • the invention furthermore relates to an apparatus for performing such a process comprising a dual-belt press and a metal foil supply roll.
  • Metal-clad laminates in particular, for the manufacture of etched printed circuit boards, must be manufactured with a surface which after the pressing is completely free of foreign matter indentations, resin residues, scratches and other surface damages which might impair the purpose of the metal cladding, namely that of presenting, after the etching of the conductive pattern, uninterrupted tracks which are insulated from one another and exhibit reproducible electric values.
  • the object underlying the invention is to improve the surface quality of metal-clad laminates and in so doing to primarily avoid thermal distortions and also keep the surface free of impurities.
  • the object is attained in accordance with the invention in that the metal foil is pre-heated while it is still wound on the supply roll, which is preferably effected by the pre-heating of the metal foil being performed by a heatable core of the supply roll.
  • the pre-heated metal foil on entering the dual-belt press to be pressed against the press belt of the press, more particularly, preferably in the region of a deflection drum of the press.
  • the metal foil may furthermore be drawn in a laterally wrinkle-free manner on the press belt.
  • the metal foil is pressed against the press belt either directly by the supply roll or by a deflection roller arranged between supply roll and press belt.
  • a deflection roller arranged between supply roll and press belt.
  • FIG. 1 shows a schematic sectional view of a dual-belt press comprising metal foil supply rolls for the continuous manufacture of metal-clad laminates
  • FIG. 2 shows a modified embodiment of an apparatus for the manufacture of metal-clad laminates
  • FIG. 3 shows an enlarged individual view of the area A in FIG. 2;
  • FIG. 4 shows a further individual view of the apparatus in the direction of the arrow B in FIG. 3.
  • the dual-belt press 1 illustrated schematically in FIG. 1 includes a machine frame with a base plate 2 and two vertical uprights 3, 4 protruding from the base plate 2. Mounted for rotation on the uprights 3, 4 are four deflection drums 5, 6, 7, 8. An endless press belt 9 and 11, respectively, preferably consisting of metal, extends around the drums 5, 6 and 7, 8, respectively.
  • the deflection drums 5, 7 on the inlet side are heatable, for example, by lines 12 for a heat-emitting medium extending inside the drum jacket.
  • the heat from the drums 5, 7 transfers to the press belts 9, 11.
  • the deflection drums 6, 8 on the outlet side are driven in the direction of the arrows and take the press belts 9, 11 along with them.
  • pressure plates 14 and 15 Arranged in the interior of the press belts 9, 11 are pressure plates 14 and 15, respectively, which are supported by the machine frame and are heated, for example, by heating pipes 13. Disposed on the surface of these pressure plates 14, 15 facing the respective press belt inside are self-contained seals 16 and 17, respectively, which grind against the press belt inside and delimit an area for the introduction of a preferably hydraulic pressure medium. It is thereby possible for heat and pressure to simultaneously act on a web of material advanced between the press belts 9, 11.
  • an electrically insulating core layer 18 is delivered as web of material at the inlet side E of the dual-belt press.
  • This core layer consists, for example, of synthetic resin impregnated paper which may be strengthened by reinforcement fibers, in particular, glass fibers.
  • the core layer 18 is drawn off from a supply roll which is not illustrated.
  • supply rolls 19, 21 for thin metal foil, in particular, copper foil are each pivotally mounted on arms 22, 23.
  • the supply rolls each comprise one core 24, 25 mounted for rotation on the arms 22, 23, with the web of metal foil wound thereon.
  • the metal foil runs from the supply rolls 19, 21 rotating in the direction of the arrows, in the region of the deflection drums 5, 7 onto the press belt 9 and 11, respectively, is taken along by the latter, is placed onto the core layer 18 and as it passes through the dual-belt press 1 is bonded under the influence of pressure and heat to this layer, so that there finally exits at the outlet side S of the apparatus a laminate which is metal-clad on either side, with the metal foils being intimately joined to the core layer. If a separating foil in the center of the core layer 18 is carried along through the apparatus, and the laminate is separated at this separating foil after leaving the dual-belt press, two laminates which are metal-clad on one side are obtained. Both rotatable cores 24, 25 of the supply roll 19, 21 are braked so that the metal foil must be drawn off from the supply roll with a certain pretension.
  • the metal foil must be uniformly pre-heated, more particularly, preferably to the temperature of the press belts 9, 11. It has been ascertained that a simple, space-saving way of pre-heating the metal foil is to heat the cores 24, 25, for example, by electrical resistance heatings or heating pipes arranged in the cores, which is indicated in FIG. 1 by the reference numerals 26, 27. Within the supply roll, the individual layers of the metal foil are snugly superimposed, which ensures good thermal conductivity contact. In this way, a completely uniform heating of the respective uppermost metal foil layer running off the roll to the desired temperature is obtained.
  • the pre-heating temperature of the metal foil may be controlled in dependence upon the press belt temperature. It is also possible to control the pre-heating temperature of the cores 24, 25 in dependence upon the temperature of the respective uppermost metal foil layer running off the supply roll.
  • strippers 35, 36 engaging both one side of the delivered metal foils and the press belts are provided.
  • Engaging the metal foils is preferably an elastic lip 37, consisting, for example, of rubber, while a peeling blade 38 at an angle which is as acute as possible scrapes off any resin residues from the press belt.
  • the aforementioned parts 37, 38, as is apparent from FIG. 1, may be joined to form a continuous channel. Foreign matter reaching this channel after removal from the metal foil or the press belt may be guided out of the casings 31, 32 by a solvent or flushing agent. After appropriate filtration, the solvent or flushing agent may be used again.
  • friction rolls 39, 41 may be arranged in the region of the deflection drums 5, 7 where they engage the metal foils deposited on the press belts 9, 11 and draw these in a laterally wrinkle-free manner. The design and arrangement of these friction rolls will be described hereinafter.
  • the strippers 35, 36 are urged in a conventional manner with a certain pressure against the surfaces to be cleaned. Since in the embodiment according to FIG. 1, the diameter of the supply roll 19, 21 constantly decreases, there is associated with the strippers 35, 36 in a manner known per se a follow-up device which ensures that the lip 37 always snugly engages the uppermost metal foil layer of the supply roll.
  • FIG. 2 the design of the dual-belt press 1 is illustrated merely by the most important contour lines.
  • Corresponding parts in FIGS. 1 and 2 are designated by the same reference numerals.
  • the main difference between the apparatus shown in FIGS. 1 and 2 is that in FIG. 2 the metal foil 20 does not run directly from the supply rolls 19, 21 onto the press belts 9, 11 and is not pressed by these rolls against the press belts. Instead of this, a deflection roller 42 and 43, respectively, is arranged between supply roll and press belt.
  • the metal foil 20 is drawn off from the supply rolls 19, 21 via a further deflection roller 44 and 45, respectively, guided over the deflection rollers 42, 43 and pressed by the latter in the region of the deflection drum 5, 7 of the dual-belt press 1 against the press belt 9 and 11, respectively.
  • the cores of the supply roll 19, 21 are also heated and ensure uniform heating of the delivered metal foil 20.
  • Energy storing means for example, in the form of piston-cylinder-units 46, 47 engage the deflection rollers 42, 43 and ensure that the metal foils are uniformly pressed against the press belts.
  • the supply rolls 19, 21 and the deflection rollers 42, 43 are again arranged in a clean air area 48 and 49, respectively, encapsulated by a casing 31 and 32, respectively.
  • the clean air areas 48, 49 furthermore comprise standby supply rolls 51, 52 for metal foil. These supply rolls are employed when the supply rolls 19, 21 are used up. Strippers 35, 36 are also provided again for removal of impurities from the metal foil and the press belt.
  • FIG. 3 is a strongly enlarged illustration of the arrangement of the stripper 35 and the deflection roller 42.
  • the stripper 35 again consists of an elastic lip 37 engaging the metal foil 20 and of a peeling blade 38 which is firmly connected thereto and engages the press belt 9. Since the deflection roller 42 and the deflection drum 5 constitute appropriate abutments for the lip 37 and the blade 38, these stripping devices can engage the respective surfaces with substantial pressure, which improves the cleaning effect.
  • the lip 37 and the blade 38 again form a channel which is closed at the end and from which foreign matter may be removed by, for example, a flushing solution.
  • the stripper 35 is arranged directly at the free edge of a common wall 53 of the casings 31 and 33. In this way, the stripper 35 simultaneously acts as seal for these casings in the inlet area of the metal foil 20.
  • FIG. 4 shows how the aforementioned friction rolls 39 engage the metal foil 20 in the region of the deflection drum 5.
  • the axes 56 extend obliquely to the direction of advance V of the metal foil 20 so that the friction rolls 39 engaging the foil produce a force component which is directed respectively towards the edge of the foil and by means of which the foil is drawn in a laterally wrinkle-free manner.
  • the metal foil supply rolls 19, 21 are arranged at the inlet side E of the apparatus. In modified embodiments, these supply rolls together with their accessories could also be arranged in a corresponding manner at the outlet side S.
  • the pre-heated metal foil is thereby deposited under pressure in the region of the deflection drums 6, 8, respectively, at the outlet side, onto the press belts 9, 11 and guided by these belts to the inlet side E. Since, in this case, the metal foil rests for a lengthy time on the press belts before being united with the core layer 18, a particularly intimate temperature and heat exchange can be effected between press belt and metal foil. It is also possible to deposit the pre-heated metal foil on the strand of the press belts 9, 11 stretched out between the deflection drums at the top and bottom, respectively.
  • the peeling blade 38 may likewise be replaced by a lip made of rubber or another elastic material. This lip is again preferably integrally connected to the lip engaging the metal foil and may form a channel therewith. It is also possible to allow peeling blades to act in a stripping manner at the press belt and elastic lips at a place spatially separate therefrom.
